Multi-receiver authentication plays an important role in network security. Many researchers have studied the constructions and the properties of the multi-receiver authentication scheme. However, most of these schemes treat the capability of all the receivers equally. In practice, receivers may have different other than equal powers in many cases. The authors consider the new scenario in the multi-receiver authentication. The authors propose a multi-receiver authentication scheme with hierarchical structure among the receivers. The authors construct an unconditionally secure multi-receiver authentication code by using the Birkhoff interpolation. The authentication scheme is also able to send multiple messages.
